Is it possible for you to set your mailer to "Text only" if posting to =
the list? It's much easier to answer to pure Text mails...

      Hello,

      I have modified ant for our corporate use, and I thought some of =
you may be interested in the additions / changes:

      1) I modified the Ant task to accept a nested "antpath" element.  =
This is a standard path element that defines a list of sub-tasks to =
execute.  We use it to glob large nested builds.  (Note: this task =
remains completely backward compatible)

      ex:
      ...
      <ant>
        <antpath>
          <fileset dir=3D"." includes=3D"*/**/build.xml" />
        </antpath>
      </ant>
      ...
Loops are not our friends :-) (if someone wishes to get them included =
into ant-core...)=20

How about:=20

    <script language=3D"javascript"> <![CDATA[
        var ant =3D myProject.createTask("ant");
        var echo =3D myProject.createTask("echo");
        var fileset =3D myProject.createDataType("fileset");
       =20
        fileset.setDir(new java.io.File("."));
        fileset.setIncludes("*/**/build.xml");
       =20
        var dirScanner =3D fileset.getDirectoryScanner(test);
        var files =3D dirScanner.getIncludedFiles();
       =20
        for (i =3D 0; i < files.length; i++)=20
        {
            file =3D new java.io.File(files[i]);
            dir =3D file.getParent();
            antfile =3D file.getName();
            ant.setDir(new java.io.File(dir));
            ant.setAntfile(antfile);
            ant.execute();
        }
    ]]></script>


Your number 2 could be

    <script language=3D"javascript"> <![CDATA[
   =20
        var ant =3D myProject.createTask("ant");
        var echo =3D myProject.createTask("echo");
        var fileset =3D myProject.createDataType("fileset");
       =20
        fileset.setDir(new java.io.File("."));
        fileset.setIncludes("*/**/build.xml");
       =20
        var dirScanner =3D fileset.getDirectoryScanner(test);
        var files =3D dirScanner.getIncludedFiles();

        if (files !=3D null && files.length !=3D 0) =
myProject.setProperty('sub.build.exists', 'true');
       =20
    ]]></script>


The last one can not be solved by <script>, but should be possible using =
.bat-files. (At least on NT or W2K). Complexity depends on your =
requirements. If one target and up to 8 variable properties are enough =
for you and it's not a problem if you end up with properties containing =
"" (space) you can=20
1. remove everything between ":start" and ":doneArgs"
2. Change the command-line after ":runAnt" to=20
 %_JAVACMD% -classpath %LOCALCLASSPATH% -Dant.home=3D"%ANT_HOME%" =
%ANT_OPTS% org.apache.tools.ant.Main %1 -Darg1=3D%2 -Darg2=3D%3 =
-Darg3=3D%4 -Darg4=3D%5 -Darg5=3D%6 -Darg6=3D%7 -Darg7=3D%8 -Darg8=3D%9

    3) I modified Main to accept only one task at a time.  All =
additional arguments are translated into user-properties. (This one is =
NOT backward compatible)
Yeah, I was thinking of going that route, but I'm way better at Java =
than at .bat or sh scripts.  (Can this even be done on a windows =
environment??).  Anyway, I agree with your assessment on this last item, =
but I strongly believe ant needs both a conditional, and a looping task. =
Has this idea already been shot down?
